I say just give it alittle time they will be best friends. I had my little Brownie for 2 years before we got our first yorkie Princess. She gave me the cold shoulder for a few days and still will not sit in my lap if someone else is already there but she loves her new sister now they are always playing. Also just a few weeks ago we got a new little boy yorkie and they are all playing together great so I say just give it a little time. Also keep giving her attention of her own. She will learn to love the new little guy. Good luck they are both so cute.
